Abstract
A damping or return device for sliding door leaves or drawers, particularly for furniture, is provided. The device has a first trolley, which is associated with a door leaf and is slideable with respect to an item of furniture, by a diametrically differently-polarized magnet, which is associated with the first trolley or with the item of furniture, and by at least one steel plate, which is associated with the item of furniture or with the first trolley. The first trolley interacts selectively with at least one elastically compressible element which abuts, in opening and in closing, with an abutment element which is associated with and protrudes from the item of furniture.
Claims14
A damping or return device for furniture comprising:
- a first trolley configured to be attached to a door leaf of an item of furniture to slide the door leaf in a longitudinal direction during opening and closing, wherein the first trolley has a central body being substantially parallelepiped in shape,
- a magnet being polygonal in cross-section and formed of first and second portions having opposing polarities, the first portion coupled to and superimposed over the second portion in a polarity direction transverse to the longitudinal direction, the magnet attached to the first trolley,
- two planar steel plates spaced apart in the longitudinal direction and attached to the item of furniture or the first trolley and arranged parallel to the magnet, wherein one of the two planar steel plates is arranged proximate to a lateral wall of the item of furniture that corresponds to a closed condition of the door leaf, and the other of the planar steel plates is arranged proximate to a first abutment element which protrudes from a top in an area that corresponds to a condition in which the door leaf is open;
- an abutment element configured to protrude from the item of furniture;
- at least one elastically compressible element disposed on the first trolley, and arranged to damp movement in opening and in closing when the elastically compressible element abuts the abutment element;
- and
- a pair of elastically compressible elements, wherein one of the pair of elastically compressible elements abuts the lateral wall of the item of furniture in the closed condition and the other of the pair of elastically deformable elements abuts the abutment element in the open condition,
- wherein each of the elastically compressible elements comprises a spring positioned above the magnet.

A damping or return device for furniture comprising:
- a first trolley configured to be connected to a door leaf and configured to slide in a longitudinal direction with respect to an item of furniture to move the door leaf in opening and closing;
- a single magnet formed of first and second portions being generally planar and coupled opposite each other so each of the first and second portions have opposite polarities in a polarity direction transverse to the longitudinal direction, the magnet configured to be coupled to one of the first trolley or the item of furniture;
- two planar steel plates positioned parallel to the magnet and configured to be coupled to the item of furniture or the first trolley, wherein one of the two planar steel plates is arranged proximate to a lateral wall of the item of furniture that corresponds to a closed condition of the door leaf, and the other of the planar steel plates is arranged proximate to a first abutment element in an area that corresponds to a condition in which the door leaf is open;
- at least one abutment element configured to protrude from the item of furniture;
- and
- a pair of elastically compressible elements disposed on the first trolley and arranged to damp movement in opening and in closing when the elastically compressible element abuts the abutment element,
- wherein one of the pair of elastically compressible elements abuts the lateral wall of the item of furniture in the closed condition and the other of the pair of elastically deformable elements abuts the abutment element in the open condition,
- wherein each of the elastically compressible elements comprises a spring positioned above the magnet.

A damping or return device for furniture comprising:
- a first trolley configured to be connected to a panel and configured to slide in a longitudinal direction with respect to an item of furniture to move the panel in between an open position and a closed position;
- a magnet being generally planar and having a polarity direction transverse to the longitudinal direction, the magnet configured to be coupled to one of the first trolley or the panel of the item of furniture to slide in the longitudinal direction in opening and closing;
- two planar steel plates positioned parallel to the magnet and configured to be coupled to the item of furniture or the first trolley, wherein one of the two planar steel plates is arranged proximate to a lateral wall of the item of furniture that corresponds to a closed condition of the door leaf, and the other of the planar steel plates is arranged proximate to a first abutment element in an area that corresponds to a condition in which the door leaf is open;
- at least one abutment element configured to protrude from the item of furniture;
- and
- a pair of elastically compressible elements disposed on the first trolley and arranged to damp movement in opening and in closing when the elastically compressible element abuts the abutment element,
- wherein one of the pair of elastically compressible elements abuts the lateral wall of the item of furniture in the closed condition and the other of the pair of elastically deformable elements abuts the abutment element in the open condition,
- wherein each of the elastically compressible elements comprises a spring positioned above the magnet.
